本文提出了一种针对2用户MIMO X信道系统，采用最小总均方误差准则，在每个发射机功率约束下，联合设计线性发射机和接收机的干扰对准（IA）方案。考虑到信道估计误差，我们进一步提出了IA的鲁棒设计。采用迭代法求最优解。仿真结果表明，所提方案优于现有方案，收敛速度快。
In this paper, we propose a new interference alignment (IA) scheme designing jointly the linear transmitter and receiver for the 2 user MIMO X channel system, using minimum total mean square error criterion, subject to each transmitter power constraint. Considering the channel estimation errors, we further propose a robust design for the IA. Iterative method is used to obtain the optimal solutions. Simulation results show that the proposed schemes outperform the existing with fast convergence.
